IMPROVEMENT IN BARREL-MACHINES.

Specification forming partof Letters Patent No. 43,074, dated June 7, 1864.

To @ZZ whom t may concern.'

Be it known that l, B. W. GEORGE, of Richmond, in the county of Sagadahoc and State of Maine, have invented a new and useful Machine for Cutting Barrel-Heads; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation ofthe same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure lis aside elevation; Fig. 2, a central section ofthe flan ge-wheel 5 Fig. 3, a front elevation of the flan ge-wheel, with its appendages 5 and Fig. 4, a plan of the vibrating table and clamping appara tus.

Like parts are indicated by the same letters in all the drawings.

The nature of my invention consists, first, in the employment of a flanged wheel, B, provided with sectional saws M M, sectional spurs or smoothers J J, a cutter, L, so arranged as to take out the stock left between said saws and cutters, and a chamferingknife, O5 second, in arranging the champing apparatus within the circle described by the spurs and saws, so that the sections of the barrel-head may be firmly held thereby, both before and after the cutting is done 5 third, in providing the wheel B with a shoulder, n, to prevent the stock from entering too far, and a depression, o, to receive the clamping arms a inside ofthe stock or head 5 and, fourth, in the peculiar arrangement of the gagepins Z and q in the holding-table W, so that a strip or section of a barrel-head, whether it be wide or narrow, will thereby not only be kept from turning but will also be centered-that is, the center between the two sides of the strip or section will always correspond with the center of the flanged wheel B-so that the two segments to complete the circular head each side of said central section will be of an equal width. y

To enable others skilled in the art to make and use my invention, lwill new describe its construction and operation.

A is the wooden stand or frame-work ofthe machine.

' B is a cast-iron wheel, fast to one end of the shaft C, as represented in Fig. l. The inside m, as shown in Figs. 2 and 3, to prevent the critters from gouging.

J J are spurs or smoothing-cutters, attached each side of the flange m, as represented in Figs. l and 3, the outer cutter being held in place by means of the metallic clamp K, which is confined by screws to the periphery of the wheel. The inner cutter is confined by screws a little less than the length of the critters, the cut or mortise being continued through the wheel, as shown in Fig. 3. As the wheel moves in the direction of the arrow, Fig. 1, the cutters J will obviously make a drawing cut, and consequently smooth.

L is a plane or cutter arranged in a mortise in the wheel just behind the spurs J J, the flan ge m being cut away to receive it, as shown in Fig. 3. This plane L is confined by means of a wedge, or in any other obvious manner, the design of said plane being to remove the stock left between the spurs J J.

M M (see Fig. 3) are short saws'attached to the wheel B and flange m as the spurs J J are, N being a clamp similar to the clamp K. llhese saws may be removed or used in connection with the spurs J J, as required. For hard wood it is better to use both the spurs and saws; for pine and soft wood, the spurs being short removable sections, are readily sharpened and kept in working order.

0 is the chamfering-knife, the shape and position of which are shown in Figs. 2 and 3, being confined by means of screws t t, so as to be-readily removed when required.

E is a treadle, one end of which is pivoted to the frame A, as seen in Fig. l.

F is a vibrating rod, pivoted at its lower end to the frame A, its upper end being provided with a fork, G, which enters an annular groove near the end of the shaft O.

H is a rod connecting treadle E with lever F.

in the position represented in Fig. l. By depressing the treadle E it is obvious that the wheel B will 4be forced outward from the frame A.

v of this wheel is provided with a circular flange, v l? is a disk attached to the outer end of a entering the wheel. The flange m is cutaway alone are sufiicient. These saws and spurs,

lis a spiral spring, the action of which is to throw back and hold the shaft C into and shaft which extends nearly half-way through the center of the shaft C, as shown in Fig. 1.

Q is a pin fast in the inner end ofthe shaft of 1), and sliding freely in a longitudinal slot inthe shaft G.

S is a spiral spring encircling the shaft C, one end resting against the drivin g-pulley D and the other against the washer R, the action of said spring being to force the disk P out, as shown in Fig. l, and cause it to press against the stock to be cut and help to confine the same. It is also used without the clamps a a, for cutting the heads of pails,tubs, and small vessels.

NV is a wooden table, the shape and size of which are clearly shown in Figs. 1 and 4, being pivoted at its lower end to the frame A at X, so as to be either raised into a perpendicular position, as when the machine is cutting. or lowered, as in Fig. l, to receive the stock.

U and V are upright arms or continuations of the frame.

T is a lever pivoted at a to the top ot' U and passing through a slot in the top of V, the outer end of said lever T being provided with a notch, Z, into which the projections Y of the table W catch and hold the latter in a perpendicular position when required.

a a are clamps, the shape, size, and position of which are shown in Figs. 1 and 4,11 b being arms framed into the upper ends of a a., and passing freely through slots in the table W, and held in place by the pins c 0.

d dare arms framed into the clamps a a., near their centers, and passing freely through slots in the table XV.

f f are cam-levers attached to the ends of the arms d d by means of the pins e e, by depressing which cam-levers it is obvious that the clamps a a may be brought with force against the stock placed to be cut between them and the table NV.

fu is a spiral spring, the action of which is to throw the clamps a t from the table W.

g, Fig. 4, is a strip of wood or metal attached to the under side of the clamps a a., and intended to operate in combination with them to hold the stock.

i. Fig. 1, is an adjustable pin or block which slides freely in the slot p, Fig. 4.

j is a graduated slide attached to the back ofthe table W by means of a screw, 7c, which passes through a longitudinal slot in j. In the lower end of the slide j is fastened the pin or block t', the design of said pin being to operate as an adjustable gage in putting in the stock to be cut, as represented in Fig. 4, the section to bc cut being represented by the dotted lines r r r r, the two sides of which are parallel.

q and l are pins inserted in holes in the table W at equal distances from the center a', and also at an equal distance each side of the longitudinal center 'w w. Thus when a strip of stock r r r 1^,whether wider or narrower, is placed on the table W so as to touch the two pins q and Z, the center of said strip willY always correspond with the center mot the table, and also with the center ot' the aXle G of the flanged wheel B, and the tWov segments each side of the strip i" r r r, to complete the circle, will be equal. The Width of said segments being thus determined and the gage i adjusted to it, another strip of stock, s s s s, is selected, of the proper width to make said segments without waste, and inserted horizontally, as represented in Fig. 4, and cut, first one edge up and then the opposite. By this means a great saving of stock is attained over the usual method of forming heads of barrels, Src.

h 7L are the legs ot a frame pivoted at e to the arms d d to support the table W when in the position represented in Fig. 1. The stock to be formed into heads being inserted under the clamps and properly confined thereby by depressing the cam-levers f f, the table W is carried up into a perpendicular position, where it is held by the catch Z. The operator then depresses the treadle E with his foot, which causes thc wheel V to be thrown forward, so that its saws and cutter shall enter the stock to be cut and perform the operation with great rapidity. As the stock, after being `cut into heads, is apt to shrink laterally, al-

lowance may be made therefor in cutting the segments by means ofthe gage i, so that, even after the stock has shrunk, the head will be a perfect circle.

Having thus described the construction and operation of my improvement, what I claim as new, and desire to secure by Letters Patent, is-

`1. Arranging the pins q and Zin the table WV, substantially as set forth, and for the purpose described.

2. The combination of the ange m, spurs J J, saws M M, cutter L, and chamferingknife O, when constructed and operating substantially as described.

3. The clamping apparatus and table W, when arranged and opera-tin g substantially as described.
